Navien, Irvine, California, introduces the NPN-Universal series (indoor or outside with vent cap) and NPN-Exterior series (outdoor only). The non-condensing tankless series comes with NaviTech technology that includes a stainless-steel heat exchanger and an advanced stainless-steel burner with the same low nitrogen oxides level as their NPE series. Both the NPN-U and NPN-E have built-in recirculation control, air pressure sensor, water adjustment valve and mixing valve. It is designed with a pin-to-pin matching configuration to make retrofits easier.
